The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Dr. Francis Halzen, the recipient of the Nobel Prize in Physics, sheds some light on the mysterious, subatomic particles that ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

In physical sciences, subatomic particles can be composite particles, such as the neutron and proton, or elementary particles. Based on the standard model, elementary particles are not made of other ...

Pions are subatomic particles that help bind matter at some of the smallest scales in nature. They are closely connected to the strong nuclear force, the fundamental force that holds protons and ...

Muons are one of the key subatomic particles for discovering new physics, but tracking them after particle collisions can be difficult and prone to error. A new study ...

Over a century ago, Ernest Rutherford discovered the proton by splitting the atom in a laboratory in Manchester. Today, researchers based in Manchester have discovered a new particle that Rutherford ...

Researchers can use the Standard Model of Particle Physics to make very accurate predictions about how subatomic particles interact and decay. However, there are gaps in the Standard Model that ...

Naples, Italy — Beneath the honking horns and operatic yelling of Naples, the most blissfully chaotic city in Italy, archeologist Raffaella Bosso descends into the deafening silence of an underground ...
